Yadda Ake Gujewa Fashewar Kayayyakin Carbide Extrusion Siminti

An saba amfani da fasahar extrusion foda don samar da samfuran tungsten carbide da sandunan carbide a cikin samar da samfuran carbide tungsten. Cimintin carbide extrusion shine yuwuwar samar da fasaha a cikin samar da siminti na zamani. Duk da haka, samfuran extrusion har yanzu suna iya bayyana fashe yayin aikin samarwa. Wannan labarin zai yi magana game da yadda za a kauce wa fasa a cikin ciminti carbide extrusion gyare-gyare.

Hanyar extrusion tana da banbancin sa idan aka kwatanta da fasahar gyare-gyaren gargajiya da fasahar latsawa ta isotactic. Tsarin samar da simintin gyaran gyare-gyare na simintin carbide ya haɗa da matakai masu zuwa: haɗuwa da foda da wakili → gyare-gyaren gyare-gyare → shirye-shiryen ƙonawa → vacuum sintering → kammala samfurin marufi → gama samfurin. Tsarin samarwa yana da sauƙin gaske, amma yana da sauƙi don samar da fashe kayan sharar gida idan akwai sakaci yayin samarwa.

Akwai dalilai da yawa don fashe, irin su saitunan tsarin da ba su da ma'ana na extrusion mutu, wakili mara kyau na gyare-gyare, ƙarancin gyare-gyaren gyare-gyare na cakuda, tsarin extrusion mara dacewa, tsarin pre-sintering, da tsarin sintering, da dai sauransu.

Tasirin wakili na gyare-gyaren extrusion akan fasa:

Idan amfani da paraffin ko A-type gyare-gyare a ƙarƙashin yanayin extrusion iri ɗaya, ƙara da yawa ko rashin isassun kayan gyara duka biyun zai haifar da tsagewa akan samfuran, A al'ada, ƙimar kakin paraffin ya fi na nau'in gyare-gyaren nau'in A. Sabili da haka, a cikin tsarin samar da samfurori na simintin carbide extrusion, zaɓin wakili mai ƙira da adadin sarrafa abubuwan gyare-gyare suna da mahimmanci.

Tasirin ƙimar dumama pre-sintering:

Ƙarƙashin samfurin da aka kammala yana da alaƙa da ƙimar dumama. Tare da haɓaka ƙimar dumama, fashewa yana ƙaruwa. Don rage fasa a kan samfurin, hanya mafi kyau ita ce amfani da ƙimar dumama daban-daban na pre-sintering don girma dabam na samfuran da aka gama.

Don taƙaitawa, don rage abubuwan fashewar samfuran simintin carbide extrusion, yana da mahimmanci a san abubuwan da ke gaba. Ya kamata a sarrafa tsarin samar da samfuran siminti na carbide extrusion. Mai samar da nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in (A) yana da mafi kyawun tasiri akan hana fasa a cikin samfuran. Bugu da kari, pre-sintering dumama adadin extruded kayayyakin yana da alaka kai tsaye da faruwa na fashe sharar kayayyakin. Yin amfani da ƙimar dumama a hankali don manyan samfura da amfani da saurin dumama don ƙananan samfura suma hanyoyi ne masu tasiri don guje wa sharar fashewar siminti na siminti.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
